Question

A particle moves from position r1 =3i+2j-6kvto position r2 = 14i+13j+9k under the action of force 4i+j+3k newton. Thework done by tgis force will be

Answer 1

hey buddy here is your answer by

UDIT

work done = FORCE× DISPLACEMENT

here Force =4i+j+3k

and displacement (r2-r1)

=11i+11j+15k

then WORK=(4i+j+3k).(11i+11j+15k)

=44+11+45 joule

100 joule
